CLIPPING-MAGHINE.

isomer.

To all whom may concern:

Be it known that I, FERDINAND E. K'Aurr- MANN, a citizen of the UnitedStates, and a Union, and State of New Jersey, have invented certain newand useful Improvements in Clipping-Machines, of which the following isa specification.

' This invention relates to an improved clipping machine adapted for anumber of purposes,but used largely'in clipping velour articles, such asvelour hats.

'for a long time.

The device is portable, having a handle by means of which it ismanipulated, and is passed over the hat or other article and has acutter which is usually driven by means of flexible shafting. I v

The present invention is designed to provide' a clipping machine of thiskind in which the cutting is done more evenly than heretofore, theclipping machine can be used for along time without dismantling toresharpen the cutting blades, and the stationary cutter against whichthe cutting blades operate can be adjusted so that it presents a goodedge to the cutting blades The invention further consists in improveddisposition and construction of parts more fully described hereinafterand also embodied .in the claims. Y

In the drawing which illustrates one-form of my improved clippingmachine, Figure 1 is a side View of the machine with art of the handlebroken away to more f ly disclose the construction. Fig; 2 is a top viewof the machine shown in Fig. 1.. Fig. 3 is a section of the front partof the machine on a plane indicated by line 3 in Fig. 2, and Fig. 4; isa section of a bearing for the rotating cutter, taken on a planeindicated by line 4 in Fig. 3.

The body portion or frame of the machine comprises a frame or casing 10,which is preferably box-like with side walls 11 and 12, a rear wall 13and a curved front wall 14, which extends to the top of the casing toform a guard or shield for the rotary cutter of the machine and has acurved lower portion 15 which terminates short of the bottom to permitthe for or hair that is to be trimmed to be engaged by the rotarycutter.

The rotary cutter is mounted. on a shaft 16, which is adapted to haveits projecting end attached to a flexible shaft, and a bearing 17receives the shaft and also has a Patented June 24,1919.

' vscrew-threaded lug 18 to receive thecasing of the flexible shaft.

The plug or bearing lug 19 is screwed into the wall 12 and projectsmaterially from the inner face to provide suflicient and adequate bearng for the cutter and its shaft. The lug 1s recessed, as at 20, toreceive the end of the shaft 16, and the cutter has a sleeve 21 securedto the shaft 16 by suitable means, such as a screw 22, which sleeveembraces the pro jecting part of the lug 19. They thin side' wall of thecasing would provide only a narrow bearing, but this structure provldesa bearmg of adequate length to keep the parts alined. 1 A suitable oilhole 23 permits lubrication. The sleeve 21 has lugs 24 properly spaced,and to these lugs are secured the blades 25, which are preferably formedas parts of helices and have 0 enings 26 in rear of their .cutting edges2 the advantages of this construction being set forth hereinafter.

The rotating cutter operates against a stationary cutter, and for thispurpose I utilize the front end of the floor plate 28, the floor platehaving a smooth bottom and being designed to slide along the surface ofthe goods being clipped.- The floor plate is adapted to be swung in adirection longitudinal to the casing and to be tilted'transverselythereof. The floor plate has hubs 29 projecting into slots 30 in theside walls of the casing, ,and movable vertically therein and alsoadapted to have a limited rotation. The slots 30 are extended part wayinto the inside of the side walls to form the recesses 31, and in theserecesses are springs The stems are screw-threaded at their top ends andthe nuts 38 fit on the screwthreaded ends and bear on the top of theside walls of the casing. The stems are prevented from turning by anysuitable means, such as flattening the stemand part of the hole throughwhich it extends, as at 39. It

will be readily seen that-by adjusting the nuts 38, the pivotal support,that is, the

line on which the floor plate swings, can be raised or lowered, and thefloor plate can be tilted laterally of the casing to conform to anyslight unevenness of the rotary cutter. The floor plate has its frontport on adapted to be removable, the form shown having a cutter orshearing plate 40 whlch is screwed or riveted into place and has itsfront edge disposed so that the cutter blades of the rotary cutter shearagainst its edge and clip'the fur. The plate 40 has its front edgeturned upward and then slightly back ward to present a sharp corner 41as a shearingof the nuts 38 and the front end of the floor plate-isswung to a cutting pos tion and a sharp corner is again presented forthe 2o rotary cutter to operate against. q

ing edge. When the edge becomes worn or slightly flattened, the centeron which the floor plate swings is lowered 'by the unscrew- The machineis manipulated a'suitable handle, and in tlg, form shown the handle ismounted on the rear of the casing.

The rear of the casing has ears 42. Between the ears'fits the car 43- ofthe handle 44, the

handlebeing adjustable, in the preferred form swinging on the bolt '45which passes through the ears, and is provided with a nut 46. The boltis split, as at 47,. and in this split portion is arranged a lockingscrew- 48, which spreads the split portion and locks the nut 46 intoposition, the screw 48 being tapered and the end of the split portionbeing slightly tapered and screw-threaded to receive the screw 48.

The handle is preferably'ma'de of a frame 49 which hascheek-pieces 50which inclose the chambered part 51 that is formed on the inside of theframe '49. The floor plate 28 has a central post 52 which is adapted tobe used as a lever for swinging the floor plate longitudinally of thecasing, and one form of attaching the actuating means is by providingthe post 52 with a recessed portion 53, into which a ball 54 rests. Theball 54 .is arranged on the end of a flexible stem,

usually made of spring wire, although any other form of strand can beused, if desired, I 1 the strand or wire 55 passing back throughanopening 56 in the rear wall '13 of the casing, through a cut awayportion 57 in the car 43 of the handle, and it then passes through thechamber 51, and is provided with an end piece 58 which projectsslightlybeyond the end of the handle, and to prevent its turning in the handleis preferably made square at one portion thereof, the square portionbeing rounded on its extremity and threaded to receive the nut 59. 60

It will thus be seen that by manipulating the nut .59, the strand orwire 55 can'be gripped to pull back on the post v52 and swing the-floorplate so that its front edge is raised. If the screw is loosened, thefront edge of-the floor plate is caused to swing by means of;

the floor plate later downward, as the spring 60 exerts a pressure inopposition to the wire 55.

A suitable thumb piece 61 canbe con- I structed over the top of the ears42 to assist in guiding and holding the machine when it is beingoperated. It will be evident that the adjustment of the floor plate issuch that it can be tilted laterally'of the frame,

it can be rocked longitudinallyof the frame,

the centers on whichit-is moved are adjustable vertically, and'theadjustment of the front or cutting edge of the floor plate with therotary cutter is assured.

When the device. is in operation, the

handle is used to guide the machine so that the floor plate glides alongthe fur to be clipped, and the fur is cut off by the contact of theblades of the rotary cutter with the front cutting edge of the floorplate. The ecesses,, or open parts 26 in the cutter blades'permitltheifpassage of air when the, cutter is rotating at a highspeed, so that the air is i not forced by the cutter out through theopening between the end of the blade 15 and the front edge of the floorplate, and a suction more than a pressureisiinstituted which assists thefur in being pulled up. floor plate to becut;
